Astronomers investigate long-term variability of blazar AO 0235+164
Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, published Nov. 3 on the preprint server arXiv, shed more light on the long-term ...
Philae's extraordinary comet landing relived
On 12 November 2014, after a 10-year journey through the solar system and over 500 million kilometers from home, Rosetta's lander Philae made space exploration history by touching down on a comet for the first time. On the ...

How did supermassive black holes get so big, so early? They might have had a head start
Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centers. However, the JWST has revealed a foundational cosmic mystery.

Right now, the sun is far more active than predicted—and small satellites are paying the price
Last week, three tiny Australian satellites from Curtin University's Binar Space Program burned up in Earth's atmosphere. That was always going to happen. In fact, Binar means "fireball" in the Noongar language of the First ...

Is an 'off-year' Leonid outburst in the cards for November?
It's still one of the coolest things I ever saw. I was in the U.S. Air Force in the 90s, and November 1998 saw me deployed to the dark skies of Kuwait. That trip provided an unexpected treat, as the Leonid meteors hit dramatic ...

Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated ...
Mining old data from NASA's Voyager 2 solves several Uranus mysteries
When NASA's Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists' first—and, so far, only—close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery of new moons and rings, baffling ...
